Measuring Procedure
Once the material has been selected, follow steps 1 through 4 below to
perform a measurement.
1. While the meter is on, press the
mm/inch
button to select the cor-
rect unit of measure.
2. After applying coupling gel on the material, place the sensor firmly
against the desired measurement area.
Note:
For most applications a single droplet of coupling gel is sufficient.
3. Verify that the Coupling Indicator
appears on the display and the
coupling LED light turns on.
4. The LCD will display the measured value and will hold this value until
a new measurement is taken or until the unit is turned off.
Note:
If the coupling indicator
does not appear on the display, or the
measured values appear to be erratic, verify that there is an adequate
amount of coupling gel in between the ultrasonic sensor and the material
under test. It is also important that the ultrasonic sensor sits flat against
the material.
Auto Power Off
To preserve battery life, the meter is programmed to turn off after
approximately 1 minute of inactivity.
Setting the Sound Velocity for a Known Material
If the material under test is not pre-loaded, the sound velocity of the
material under test can be entered. To enter the appropriate sound velocity,
follow steps 1 through 9 below.
1. While the meter is on, press the
SELECT
button.
2. The display will either indicate "CdXX" or "XXXX".
3. Press the
or
arrows to scroll through the material codes until
you see the 4-digit value.
4.
This 4-digit number represents the last set sound velocity of a material.
